RUDOLF MARKGRAF, OF KANSAS CITY, MISSOURI.

PARTITION CONSTRUCTION.'

SPECIFICATION forming part of Letters Patent No. 786,826, dated April 11, 1905.

Application filed March 15, 1904. Serial No. 198,257.

To LLZZ whom, t may concern,.-

Be it known that I, RUDOLF MARKGRAE, a citizen of the United States, residing at Kansas City, inthe county of Jackson and State of Missouri, have invented certain new and usevful Improvements in Partition Construction;

andI do declare the following to be a full', clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My present invention relates to a partition construction, and has for its object to provide a partition which will be simple and economical in construction and which can be easily erected in any building.

A- further object of my invention is to provide improved details of structure, hereinafter described, and pointed out in the claim, reference being had to the drawings, forming partof this specification, in which like refer.- ence-numerals refer to like parts throughout the several views, and in which-- Figure l is a perspective view of a partitioned space, showing the rods and iiller. Fig.

2 is a similar view showing a modification of the rods. Fig. 3 is adetail View of one of the rods. Fig. 4 is a detail view showinga modification of the rod.

Referring more in detail to the drawings, 1 and 2 aren the floors of a building which are provided with my improved partition. Floors l and 2 are provided with perforations, through which is inserted a rod 5, having a bolt-head 6 at one end adapted to rest on a washer 7 surrounding rod 5 and` seated on floor 1. The opposite end of rod 5 is screw-threaded to carry a tightening-nut 8, which is separated from floor 2 bya washer 8. If it is so desired, rod 5 may be threaded on both ends and carry two tightening-nuts, so that rod 5 may be tensioned from either end. By having a series of such rods connecting the floors of ya buildnating in its passage, so that they support each f other, the bottom strip resting on the iioor, the second on the rst, and so on to the top. The ends of the strips may be anchored in any suitable manner to the sides of the building.

`My partition is adapted for either board or concrete ioors, and by having the rods tensioned in the manner described a perfectly rigidpartition is assured.

I do not wish to be understood as limiting myself to the exact details of construction herein shown and described, inasmuch as the same may be varied without departing from the spirit of my invention.

Having thus described myinvention, what I claim as new therein, and'desire to secure by Letters Patent, is-

In a partition, the combination of a series of rods extending through perforations in the floors above and below the space to be partitioned, each rod having a bolt-head at one end and being screw-threaded at its other end, a nut on the threaded end of each of said rods for tightening same, washers between said bolt-head and its adjacent iioor and between said nut and its adjacent licor, and strips of metal lath passed backward and forward between said rods substantially as set forth.

In testimony whereof IaiiX my signature in presenceof two witnesses.
